ATPA monitors in-trail separation on the final approach course. Early next year, the FAA expects to complete another phase of software improvements to ATPA. NASA has been working with the FAA to understand the effect of aircraft landing speeds on monitoring in-trail separation. The purpose of this meeting was for the FAA to share their current ATPA plans and for NASA to provide results of their relevant research. Aviation Systems Division researchers have been investigating the prediction of aircraft spacing compression during final approach using a variety of methods, and have also been developing a terminal area aircraft conflict detection algorithm and concept of operations. Both NASA and the FAA agreed to continue these meetings and expressed support for continued collaboration; the FAA agreed to provide more operational data to NASA researchers to improve the terminal area aircraft conflict detection algorithm. + Back to Top
